Abstract
The frequency and damping of free lateral linear oscillations of a viscous non-cylindrical liquid bridge, formed between two axial disks of radii R1 and R2, are computed using a recently developed semi-analytic procedure [R. Kidambi, J. Fluid Mech. 681, 597 (2011)]. A comparison with recent experimental results [E. J. Vega and J. M. Montanero, Phys. Fluids 21, 092101 (2009)] for the first non-axisymmetric mode over a range of bridge volumes is good and the damping rate is better predicted than by a one-dimensional slice model especially for highly viscous bridges. The procedure can be used to calculate the oscillation characteristics of any desired mode for any region of the parameter space.
